Lecture 4 - Image Processing

.............is a mathematical function, and it conveys some information.

• Signal

• Image

...................is a signal that is measured over time such as voice signal.

• One dimension

• Two dimension

.........................signals are those that are measured over some other physical quantities such as a digital image.

• One dimension

• Two dimension

Two dimension signals are those that are measured over some other physical quantities such as a digital image.

• True

• False

One dimension signals are those that are measured over some other physical quantities such as a digital image.

• True

• False

One dimensional signal is a signal that is measured over time such as voice signal.

• True

• False

Two dimensional signal is a signal that is measured over time such as voice signal.

• True

• False

The amplitude of f at any pair of coordinates (x, y) is called ................. of the image at that point.

• Intensity

• Gray level

• All of them

• None of them

.................. a two-dimensional function, f (x, y), where x and y are spatial (plane) coordinates.

• Signal

• Image

...................is a creation of images synthetically صناعيًا.

• Computer graphics

• Image Processing

• Computer vision

• Pattern recognition
